Carpentry- 15 Aug 2025
I would 100% recommend John and his team. We have been really unlucky with 3 other builders taking off with our money and not completing the work. John is very professional, took on someone else’s mess and done a brilliant job. We wanted exposed oak rafter detail and the team done an excellent job. John is very good at problem solving on the spot when there are issues, he is very approachable and keeps you updated with the progress throughout the job. What he has been good at is also talking through different options with us before doing different sections of the work and he does not take short cuts. If you need excellent honest builders John is your guy! We will get the decorations done and post the end product.

Rob completed a large portion of our home refurbishment, to include a knock through, kitchen installation, sky lantern installation, all new woodwork (skirting, archs etc) and media wall. I am a very fussy customer but Rob exceeded all expectations, compelting all work to a very high standard. Very professional, took the time to talk through all options before making our dreams a reality. Always left the house clean and tidy. Work was completed ahead of schedule. I do not usually write reviews but it is the least I can do as I sit in my beautifully refurbished house! Thanks Rob, I will be in touch in the future for sure.
